Letters Patent No. 106,276, dated August 9, 1870.

IMPROVEMENT IN MACHINES FOR HSKING- CORN'.

The Schedule referred tain these Letters Patent and making part of thesame.

port,.n the county of Goluinbia and State ot' New York, have inventedcertain Improvements in Corn- Huskers; and I do hereby declare that the'following is a full, clear, and exact description thereof', referencebeing had to the annexed drawing mnki ng part of this specification, inwhich- Figure l is a plan view of my improved machine.

Figure 2 is a sectional elevation on line x x, tig. l.

Figure 3 is a section of a detached portion on line y y of Iig. 1.

The same letters are used in all the figures `inA the designa-tion ofidentical parts.

This invention relates to machines for husking com, of the class whereintwo sets of rolls are employed, one for stripping theears from thestalks and the other for husking the ears as theyare delivered ffrom'the strippingor picking-rolls.

The first part ot my improvement consists in forining, upon the surfaceof the stripping-rolls, right and left-handed screw-threads andl groovesof variable pitch, so arranged, with reference to each other, that theelevations of one are opposite the grooves in the other, to enable themto nip the ears from the stalk, and draw the latter, as it passesthrough them in 'a lateral direction, away from the point where .it isfed The second part consists in providing the bushingrolls each with oneor more spiral depressions, of peculiar form, in their surfaces, whichdepressions, heilig left-handed upon one and right-handed upon the otherrclland opposite to 'each other, receive the ear as it falls fromrthepicking-rolls, and allow it to settle down between the husking-rolls, sothat the edges of the spiral bushing-surfaces shall have a continuousbite upon the husk.

' The third part consists in theapplication of an oscillating presser,in condection with husking-rolls, constructed as described, to gent-lypress upon the ears, as they pass along the surface of such rolls, for

the purpose ot' holding the ears iu firmer contact with them, so thatthe husk may be morecertainly grped by the edges of the lmskingsurfaces.

To enable those skilledjn the art to make and use my invention, I willproceed to describe its construction and operation. l

The frame A is made of strong timbers, and of suitable form anddimensions to receive and supportv the various operative parts to bemounted upon it.

The picking-rolls B B' are arranged across the front.

and in the upper portion of the trame, where their journals aresupported in suitable boxes.

Springs or elastic cushions are arranged under the boxes ot one of therolls in the usual manner.

The surfaces of the rolls are provided with spiral or screw-threads,running from end to end of' the same, and made of a variable pitch, bypreference, as shown in the drawing. i

The threads on oneroli run in a reverse direction to those on the other,Aso that, as they are revolved,

and stalks of corn arefed in at one end, they will, in 'drawing suchstalks through, carry them from theend where they are fed in to theopposite end, and there discharge them, thus permitting of constant anduninterrupted feeding.

It will be observed that the threads of one of the rolls are oppositethe grooves in the other, and mesh into them, to allow them to take afirm hold of the stalks, and facilitate the nipping of the ears.

The depth and pitch of the threads will vary 'in accordance with thenature of the work to he performed by them.

The rolls are geared together by spur-wheels Bz and B, and may bc drivenby any suitable power which should be applied to the unyielding roll.

v -The ears ofcorn, as they are nipped from the stalk, Adrop upon thehusking-rolls C Cl, which are arranged transversely under and in rear ofthe picking-rolls, in au inclined position, as shown.

, They revolve, by their journals, in boxes arranged upon thecross-beams ot' the frame, they being geared together' by the wheels I)D', tovone of whichA 'the power is applied.

One of the rolls is made yielding, by placing its journal-boxes againstsprings or elastic cushions. I propose to construct these yrolls withone or more spiral depressions, C, in their surfaces, running from endto end, and in reverse directions along the respective rolls, so that',in revolving them, such de pressions come opposite to each other on theupper surface, and i'orm a bed into'- which the ear drops.

By making these spiral depressions in the rolls, a continuous spiralbushing-surface is obtained, so that such bushing-surface or surfaceswill have a continuons bite upon the husk from the point to the but-t ofthe ear, and thus strip the husk oi1 at one operation.

Small points or teeth c may be arranged along the griping-edges of thehnsking-surtces, to assist in drawing the husk between them-,

T hold the ears, as they pass"`along the inclined bushing-rolls,infirmer contact -with them, I provide an oscillating presser, E, whichmay be constructed of a bar of iron, covered with an elastic or yieldingpad, El, and pivoted, by arms E, to the cross-beams ofthe frame, by theside ofthe bushing-rolls, extending the proper distance above them, asshown in lig. 2.

One of the arms E2 is linked to a crank-pin on the journal of one of therolls, to give to it an oscillating motion. e

I have shown only one set of husking-rolls, but'I propose to employ atleast two sets, arranged side by side in the usual manner.

Where two sets are thus used, the presser will have a sufficientoscillation to press alternately upon the ears passing over euch set.

Having described my improvements in machines for hnsking corn,`

-Wlmt l claim, and desire to secure by Letters Potent, is-

1. The picking-rolls-B B7 when the'sztme are provided with spirztlthreads and grooves, gearing with each other, and formed of variablepitch from end tov end, substantially as shown, and for the purposedescribed and set forth.

2. The husking-rolls C CI, when provided with spiral depressions G"l Cupon their peripheries, and formed as described, substantially as n-udfor the purpose set forth.l

3. In combination with the husking-rolls C O, the oscillatingpresser-bar E, substantially as and for the purpose set forth.

ln testimony whereof I have signed my name to the foregoingspe'ciiioation in the presence of two subscribing witnesses.

PETER PHILIP.'
